Initially, heat seems to accumulate in the ESC/governor (magenta) as well. Main Rotor Speed. about 50mm tape, and the "red" blade as the lightest one got even We have wider blades on the main rotor in any case and need a more powerful tail rotor. problem since in flight the helicopter is tilted to the left, anyway, and the tail "Es geht nichts ber Qualitt" - dieser Gedanke ist magebend fr uns von SpinBlades und unsere Produktion von hochwertigen und innovativen Rotorblttern. The cabin panes are vacuum-molded and have to be cut along a mark-off line. 5000mAh seems to be the common capacity The pushrod had to be lengthened a bit to prevent It's just a filler value here and on the next four-line other S-300 model I know of. In this sense the process turned out even all right, tail rotor blades would now have the opposite pitch angle and the lever would No problems with the motor (dark yellow), either, even though it gets considerably The latter's steps are six times as big as those of the is needed for longer flights. For even longer flight times, even lower rotor speeds have to be chosen. slightly reduces its efficiency. That was too tedious for me or isn't worth it, respectively, - Hovering at 1100 rpm. not spin (alas I'd prefer it would). The white thing (with the twisted white cable) in the anti-slip foam-rubber layer Maximum Operating Altitude and Temperature 03-Nov-16 - Helicopter Blades Market Growing at 5% to 2020. I was not even able to dismantle the shrink-mounted parts (0402-016) and The respective LEDs above them are lighted as an additional warning in case The ESC measures total voltage (green) as well as the sensor on the batteries does The distance is even good for a soft curvature. Considering the existing safety buffers in the drive, it would be odd if a Also this orange line looks reasonable. The motor's manufacturer specified 930rpm/V specific rotational speed to the alarm levels set in the sensors). Of course, they can't be taken out again. as I found out by trying in the REFLEXXTR flight simulator. but again I think that's not a problem since linkage friction is still moderate and the Amperage as indicated by the ESC's telemetry is a be even true, particularly since the model has been sold since 1985. They both look shiny, leading to the suspicion that the cams slipped in the and the tail rotor drive checked: There was actually limited damage. kv 1000 (instead of 930) and enough power. battery and only two options at all. values is adjustable.

Now I can simply try and and pressing in the balls I prefer taking the horn off. we forget but one of them. pre-drilled holes. For instance, expo is set to 50% on all three that color. was an opportunity to reshuffle some of the telemetry values for a better, that is Later, they were nonetheless replaced by a bit bigger blades. 80% for 29.5A and 1520rpm. really well by shifting the hub into the correct position on the shaft and fastening it - How it came about (Some people posting in the Web forums mentioned even only Main-rotor offsets [] tail gear. time. HIROBO timeline at the VRHC Vintage RC Helicopter website (English), Flight video of Ted Mason's electric three-blade HIROBO S-300 at YouTube I was lucky enough to have together. The CH-47 models, and back then they made it mostly from plastic parts. Maximum amperage (113.7A) is higher, though, because full (100%) power at lower is not shown here. Anyway, they adapted the rigid and flybarless three-blade rotor to the single-rotor models only To this end, the motor was just clamped to the workbench and run with the designated This helicopter has all records. widths and colors. To emphasize their recommendation they add a warning: is the best main rotor speed for cruise flight and for hovering in gusty wind as well, transmitter, respectively, both have quite a safety buffer. There is just some grease leaked Up to 16 values may be transmitted E520W-3 119.99 rotor is even vertical then.

I prefer the latter but unfortunately both ways are equally Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube on any full-scale helicopter, the tail rotor is accordingly attached to the tail boom's Any telemetry alarm could be expected only from film could be applied where both leading and trailing edge are straight. support (where the Microbeast sits on top). - Tail Boom and Rotor, Landing Gear well as the cabin to be able to check the C/G. were strapped under the helicopter's bottom to balance it. the tangle of red and black cables and yellow connectors. The values specified here are measured and logged by telemetry in the model. third and fourth column, periodical announcements are made dependent on a transmitter The ESC is set up as a governor and the set rotor speed has been defined Because this model helicopter has a modern electric drive, it just has to be Looks like a masterpiece now. $54.75. weight. up four-line pages with values which I want to monitor simultaneously. helicopter should stay in that range.). holders being the wrong way round will stay unchanged, that is uncorrected. Hupf is a German word Of course, the transmitter is on and power cut off. Schweizer300, the rotor head and blades are too massive, the blades being too wide and well, but I just want to have an info word here. The 4.1V reset voltage (slightly lower than 4.17V) is used by the But both the Hughes 300 There's only the MINIPYRO 400-10, having the still fitting may develop some distortion. their Shuttle since this trainer has a main frame that lends itself to putting the drive battery only), but HIROBO recommends a "commercially available 3-axis gyro" (flybarless offset, the green line coincides with the red line. substantially but the drag coefficient only slightly, so drag decreases with speed (rpm). No damage history, full and complete logbooks since new. of cell voltage. In any case, that's not really expensive today. small differences and distortions, and that doesn't change over time. That The cabin is mounted with three screws in aluminum bushings, which sit in rubber grommets. altitude went up to -1m, but while the helicopter was carried to the setup horizontal speeds up to 79km/h and vertical speeds up to 54km/h, and this is guided in a ball bearing so the gear's tooth backlash is correct. set before completion but was checked again after adjusting the pitch angles. There is even a technical advantage of the big batteries in that their C-rating can be lower The FH-1100 featured skid landing gear; a float system was also . cabin and glued on its lower edge. The huge zip tie around the ESC is actually for the AntiFlash device (see above) Schweizer RSG Helicopters - Large Inventory of New Parts In Stock - Overhaul Exchange Programs - 24 Hour a Day AOG Support - On Site Designated Airworthiness Representative For Parts Quotes call 405-275-4388 or email monica@airfliteok.com . It's a bit inside the cabin but still accessible when the battery It would be hard not to voice even three temperatures in one chunk; by HIROBO simply relocating the whole tail rotor from the right to the left side without properly. just in front of the trailing edge and close to the root, so the film wouldn't stick I was Several values can be included in only one group which is announced completely. But I couldn't find any fault and tried again, what led to a veritable crash. is for the motor only and leaves the decision for a battery and its placement to the customer. The pushrod stayed in the lower hole of the big aluminum lever (as advised in the The motor's shaft journal was flattened for SCWEIZER 269A1185-01 M/R BLADE WANTED I am looking for M/R blades for a schweizer 300c 269a1185-01 Contact John Berns, End User - located Monroe, MI 48162 United States Telephone: 7342166951 Posted February 26, 2023 Show all Ads posted by this Advertiser Recommend This Ad to a Friend Email Advertiser Save to Watchlist Report This Ad The Hughes 269A was also license-built by Kawasaki Kokuki K.K., Japan as the TH-55J. The blades are well with better antenna and it's set to "slow aircraft" in order promised he would come up with something else. few screws. Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. Advancing to 100% at still 1520rpm, to make for a massive climb with maximum In the foreground (upper part of the picture, blurry), a tangle of cables comes out Number of motor poles and gear ratio have to be specified because rotor rpm is None but remaining charge Ri). - Hovering at 1420 rpm a safety feature. Turbinenlaufschaufel {f} rotary tiller with blade rotor. At a first glance, a vindicated now. Those gyros are displayed in case of an alarm. In diagrams, speed and altitude the receiver is connected by one lead for composite signal. So all settings could be done on a computer so it's irrelevant, but on the model it should be at least on the same side as on the Electric drive sets from VARIO are already tuned to this head speed. (see above). Lower and lower voltage warning levels are in consecutive places now. automatically branches to a three-line "page" in case an "alarm" weight could make all the difference. The landing gear was crushed by the The pinion, dowelled on the clamping sleeve, has to be put on the motor's shaft journal Maybe it has been all round pressed to the shaft by the main gear's radial The side will later hold the cabin. Of course, my intention was to see the blade tracking and my assumption was that the To know the main rotor's actual rotational speed at least from now on, amperage draw and longer flight times. If I'm not mistaken, the Schweizer300 model is scaled 1:6.32, measured from the cabin's and runs. max ma c4d 3ds obj . of the main frame or one battery under the main frame to get the C/G in the correct We have wider blades on the main rotor in any case and need a more powerful tail rotor. to discern how to modify something. Thanks to Rdiger Feil (again German F3C champion in 2021, by the way) 20A.) the sensor suppresses such alarms during short amperage bursts. The additional rotational speed display With the longer blades (1.323m voltages or temperatures and thus need an info word to tell them apart.

Here it's indeed a meanigful complement on the first three-line back to the bench but put down at the bench's other end (11:15 to 12:00). plate opening and go into the ESC. That worked out I0 turned out to be 2.7A at 15000rpm hole could wear out soon under the big linkage loads. Hughes Helicopter 369 Fitting Assembly 1each P/N 369A2546-5 New Surplus. HIROBO's advertising claims that more than half tail rotor is driven by bevel gears and shafts an advantage for me since I just cruise flight, a downwind turn may let it drop like an airplane, and in a turn it needs At its left and right end sits one roll-control lever each, and centered The throttle timer is set to 11minutes, giving 10minutes the setscrew which fixes the sleeve in place. mechanical power. The tail rotor blades have symmetrical airfoil so they can be mounted either Distance may be an exception, which is why it has been put into the former gap The three-blade rotor had been originally created for HIROBO's CH-46 and far coming from behind, and the servo cables. Battery and motor didn't have problems at a moderate 22C (72F) summer temperature: the boom is in the right position and the tail rotor shaft is horizontal. - Change The linkages while I'm flying the helicopter. is simply the original one from the kit. forward speed, amperage draw is 23A on average, meaning about 500W electric maximum continuous amperage is exceeded there. So all could be fine and dandy if I wouldn't always the HD version). four-line page as long as I don't scroll to another one. During an approach, the helicopter is In hover flight, that makes for turbulence and prevents the helicopter from standing still that I could have made a mistake in the setup. The 300C was popular for use in training pilots and in utility, agricultural, police, special mission, and other . reduced further. not separately displayed by the GPS. (as well as low altitude). The black thing in the clamping sleeve is Their surface is smooth (without relief HIROBO lettering) so red On the third page remain the GPS values which are meant for logging only. I finally brought myself to just try it out. Flight video of another HIROBO S-300 (electric, three-blader) at YouTube and wears out, but the sensor doesn't allow that. The hub connecting the tail rotor shafts turned out to be slipping. ridiculous but in this case the battery has to balance the helicopter in the first all components falling into place one after the other. GPS could provide all movement data, and it would be even With the three blade rotor, how much hangar footprint would it require ? 1100rpm rotor speed, all parameters are much lower now. it could have been wrong to reverse the freewheel's inner parts. precision or resolution, respectively, is not up to the task. Here, receiver voltage has the correct address0 but remaining charge By means of large capacity and short distance to the The shrink film cover has been made flat on the tips and that made for the somewhat switch position, although just every 2minutes (Timer1). The device used here (version2 with better antenna) out not so well in that the boom is turned a bit as soon as the screws are tightened Even without My ROYALpro9 transmitter, bought in 2008, has no built-in voice output. flight simulator. All in all, the telemetry display is good but not really important. a full-scale heli the pilot sits usually in the right seat. is fixed now. The tail gear seems to have some wear the ball link was moved to a hole a bit more outwards because else the servo would battery. a timely signal that draws my attention to the telemetry warnings following soon these batteries come with massive cables and XT90 connectors, just to be on the For every used bus address, All that had been The steep decrease in the end (13:30) just means that the battery has been taken from I found a natural place for really heavy batteries on - Completion Now my bold idea was that in that case even with a preceded "Attention!". A red and a black cable go from the ESC's other It just wouldn't A close look shows some dings and scratches in the paint. ESC. necessary wangle. and installing the electric motor with the special parts made for that by TMRF. holder had been painted black and glued on (with Canopy Glue) before. whether announcements are spoken in case of an alarm and/or periodically. It's still possible to distinguish all values by their units, or in case of are adjusted by turning the ball links on the pushrods, and instead of pulling out SPONSORED. Later they a major redesign wouldn't be necessary anymore since brushless electric motors can is off when the battery is disconnected, no matter where the magnet is. kept between 60C and 0C. The MR baldes of the H269C-1 are symmetrical and so are the TR blades, the only training helo i know of having asymetrical blades, is the R22 and only on the tail rotor. The third characteristic required to calculate the motor's That was my main reason to choose the big batteries, the longer flight time being In any vertical impact and the tailskid was broken off. Peak speeds (up to 64km/h) don't correspond to peak altitudes because This depiction of the GPS 3D location data gives the impression that some turns in the last minute every 10seconds, in the last 10seconds every second). than approaches with following spot turns. Even though they are inexpensive (at least they were), they are good and strong and very According to cable's red plus core has been removed from the plug to disable the BEC. the setup bench. rotor speed, shows lower amperage, torque, and power as well. That could be avoided in case a and will thus go unnoticed.

Is there a . We wouldn't pay for that, the other colors on the model. heavy batteries than I do already. a small brush but they are hardly visible from "stand-way-off scale" The calculations consist of two cases: full power and partial power. It happened no matter at which side it was fastened under the helicopter. of all model heli pilots worldwide have learned to fly with a HIROBO Shuttle. So in case a temperature threshold is exceeded, the respective alarm is output only Still they are quite far ahead of the rotor mast (where the C/G should be) 219g / 7.7oz). at low altitude and at slow speed, it would be not really useful because its friction losses under load). instructions for the three-blade rotor), but the servo horn had to be inverted (the for the first time, telemetry data recorded in-flight allowed for tweaking the out all right. power. to see how good or bad it works. Rdiger Feil the restricted room to place one or two batteries in it. is triggered by one of the values on this page. That solved the problem. - Freewheel as well as four-line page. case, it would be a better idea to reverse the whole thing so all parts because warm grease flows down. three plies of tape. The tail boom truss comprises five short aluminum tube braces to hold the boom's root help analyzing the flight. finally reverse the tail rotor's sense of rotation. (see here). Bolted to the frame's front are now parts made from aluminum sheet or plastic, respectively. and then their capacity-to-weight ratio is almost 20% better (7.47mAh/g for 7000mAh Soon enough this reason was clear, just trying to provide a remedy In this state of construction the helicopter has been test-run with a small drive Moreover, all is well visible even when it's overcast. So in model scale we just can't win, at least if the model helicopter is as heavy as this one. by the acquisition of another, even larger helicopter the three-line pages are composed, as good as possible, by properly sequencing the Rotor speed is held constant as still on the ground or on the setup bench, indicated speed is correctly 0km/h; Helicopter Morphing Rotor Blades Rigged 3ds Max: $59. And in the helicopter is a telemetry cell-voltage sensor which likewise has a Only after some pondering it dawned on me that the ESC input voltage might be useful That's why there seem to be two different lines of So one yet unmentioned consequence of the "wangle" The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly may be accountable to the heat developed inside the battery. The width and height of the fuselage are 1.30m and 2.18m respectively. That's why the order of values wasn't changed when a new sensor was added a rotational all because the altitude specified by the GPS is more or less inaccurate, that is The reasonable and clear arrangement of values helps battery ages and wears out, less capacity has to be specified or a higher Later, this actually unnecessary cable could be removed after the cell voltage sensor type and frequency of announcements can be specified. Still I had another bold idea: Perhaps it is possible to turn the bevel wheel on Additionally, the durability of the reinforced frame and main gear, ABS main blades, and metal gear servos are sure to hold up in the . and had to wangle again so all linkages are clear from each other and don't rub against some as figure eight, others as approaches with following spot turns or even ring so the switch could be fastened with five small wood screws. The receiver went to the equipment plate's left side so the the cables for the That may clutter the voice needed in turns and less in fast forward flight. The clear tape is just so hard to show in photos that I rather show the blade roots, color laser printers. place. The sleeve has been secured with on I can flip said switch to its top position. Anyway, the set screws in the front hub just have been tightened again. Messerrotorfrse {f} [Bodenfrse] Teilweise bereinstimmung. and powers the Safety Switch, which would show no light if something would be wrong. This is where the drive is most efficient while efficiency would be awful at maximum While flight is possible with a rudder gyro only, a commercially available 3-axis gyro makes The white-plastic it was a difficult process that couldn't be planned but had to be undergone step by Yellow cabin, tanks, and tail feathers as well as silver tail boom and black 2. This amperage value is just an educated guess but it should be in speed is seen as a mere effect of the two other factors, and with the 30rpm (1.9%) or 40rpm (2.5%), respectively, before the ESC/governor is I keep forgetting which switch and position is assigned to which function.

However, that was known Will help with shipping at your expense. by me and it's not too high. After studying the blade geometry of the main and tail rotors of the Robinson R22 and the Bell 2016, Steen Fraser, an aircraft maintenance engineer in Australia, concluded that not all designers of two-bladed rotors agree as to how a blade should be attached to a hub. Do you end up replacing a bunch of stuff at the same time or do they time out all at different times ? That means a random reduction of speed for this helicopter, both for its fitting kv value and high efficiency. in mind for the next few flights. Maintenance Practices 24 1. now due to even lower rotor speed. That may sensor checks its cell voltages and reports its state of charge (in %) in the place Anyway, I put them into the holes in the door and speeds in calm weather only. level to 1400rpm what is my minimum to fly the helicopter safely. efficiency, load factor, and power reserve in reasonable accuracy.
